Introduction
Thank you very much for purchasing a ZOOM
Audio Converter.
The
has the following features.
Thunderbolt™
18-in/20-out Thunderbolt™ audio converter
The
audio converter uses Thunderbolt™, the latest
generation of high-speed interface technology. With this, we have
realized a system with low latency that was not possible using USB
2.0. Since it supports recording and playback at up to 24-bit/192kHz,
it can also be used to play back high-resolution sound sources and
deliver them with superior audio quality over the Internet.
Attention to audio performance
An asynchronous transfer system that is not impacted by computer
jitter is used. The latest AD/DA converter, which supports 192 kHz, is
used. So, the entire system reproduces the original audio faithfully.
02
Built-in high-performance mic preamps
The high-performance mic preamps are based on those developed
for our H Series. Hi-Z input is supported. The gain can be raised by
up to 60 dB, and +48V phantom power can be supplied.
Flexible built-in mixer and dedicated
application
mixer
The
has a built-in mixer that allows you to freely route up
to 20 output channels from among the 18 input channels and 20
computer playback channels. By using the
application
designed for this interface, you can make settings for the built-in
mixer and monitoring effects from a computer.
For details about
, see the ZOOM website (http://www.
zoom.co.jp/downloads/).
Please read this manual carefully to fully understand the functions
of the
so that you can make the most of it for many years.
After reading this manual, please keep it with the warranty in a safe
place.
Safety Precautions
In this operation manual, symbols
are used to highlight warnings and
cautions that you must read to
prevent accidents. The meanings of
these symbols are as follows.
Something that could cause
Warning serious injury or death
Something that could cause
injury or damage to the

Warning
Warning
Alterations
Do not open the case or modify the
product.
Operation using an AC adapter
Never use any AC adapter other
than a ZOOM AD-19.
Always hold the AC adapter itself
when disconnecting it from an
outlet.
Do not do anything that could
exceed the ratings of outlets and
other electrical wiring equipment or
supply power other than AC100V.
Before using the equipment in a
foreign countr y or other region
where the electrical voltage differs
from AC100V, always consult with
a shop that carries ZOOM products
and use the appropriate AC adapter.
Caution
Warning
Product handling
Do not drop, bump or apply
excessive force to the unit.
Be careful not to allow foreign
objects or liquids to enter the unit.
Operating environment
Do not use in extremely high or low
temperatures.
Do not use near heaters, stoves and
other heat sources.
Do not use in very high humidity
or where it could be splashed by
water.
Do not use in places with frequent
vibrations.
Do not use in places with much
dust or sand.
Connection cables and input/
output jacks
Always turn the power OFF for all
equipment before connecting any
cables.
Always disconnect all connection
cables and the AC adapter before
moving the unit.
Volume
Do not use at a loud volume for a
long time.
Usage Precautions
Interference with other electrical
equipment
In consideration of safety, the
has been designed to minimize its
emission of electromagnetic waves and
to suppress interference from external
electromagnetic waves. However,
equipment that is very susceptible to
interference or that emits powerful
electromagnetic waves could result
in interference if placed nearby. If this
and the other
occurs, place the
device farther apart.
With any type of electronic device
that uses digital control, including the
, electromagnetic interference
could cause malfunction, corrupt
or destroy data and result in other
u n ex p e c t e d t r o u b l e . A l ways u s e
caution.
Rack mounting
If you are unable to mount the
in the rack you are using, remove the
rubber feet from its bottom panel.
Cleaning
Use a soft cloth to clean the exterior of
the unit if it becomes dirty. If necessary,
use a damp cloth that has been wrung
out well to wipe it.
Never use abrasive cleansers, wax or
solvents such as alcohol, benzene or
paint thinner.
Temperature considerations
Continuous use of this interface for
long periods of time, for example,
might cause it to become warm. This is
normal as long as it does not become
too hot to touch.
it immediately. Cont act the store
where you bought the unit or ZOOM
service with the following information:
product model, serial number and
specific symptoms of breakdown or
malfunction, along with your name,
address and telephone number.

NOTE
When shipped new from the factory, the AD/DA converter upsampling
function is enabled. This will cause operation with a 4x sampling
rate when the sampling rate is 44.1/48 kHz. See the
Reference Guide to disable it.
Upsampling
When the original sampling rate is 44.1 kHz or 48 kHz, internal
processing can allow operation at 176.4 kHz or 192 kHz (enabled
when shipped new from the factory). This eliminates aliasing noise
from the sound during A/D conversion and makes the sound with D/
A conversion even clearer than before.
